Abstract (en)
[origin: EP4030845A1] This application discloses a communication method and apparatus. The communication method and apparatus are applicable to an Internet of Vehicles, or are applicable to fields such as D2D, intelligent driving, and intelligent network connected vehicles. The method includes: A network apparatus determines an i<sup>th</sup> sidelink transmission resource of an i<sup>th</sup> cooperation terminal apparatus, where the i<sup>th</sup> cooperation terminal apparatus belongs to N cooperation terminals, the i<sup>th</sup> sidelink transmission resource belongs to the 1<sup>st</sup> sidelink transmission resource to an N<sup>th</sup> sidelink transmission resource, the i<sup>th</sup> sidelink transmission resource is different from a j<sup>th</sup> sidelink transmission resource, the j<sup>th</sup> sidelink transmission resource is a sidelink transmission resource that is of a j<sup>th</sup> cooperation terminal apparatus and that is determined by the network apparatus, the i<sup>th</sup> sidelink transmission resource is used by the i<sup>th</sup> cooperation terminal apparatus to send second data to a target terminal apparatus, the second data is determined based on first data sent by the network apparatus to the i<sup>th</sup> cooperation terminal apparatus, and the N cooperation terminal apparatuses and the target terminal apparatus belong to a same cooperative transmission group. The network apparatus sends the i<sup>th</sup> sidelink transmission resource to the i<sup>th</sup> cooperation terminal apparatus and the target terminal apparatus.
